| 研究開始時の研究の概要 |
Utilizing low price, non-toxic Mn catalysts provides safer and more economical routes for synthesis of these valuable products. This will eventually have a large impact on synthetic organic chemistry and closely related pharmaceutical/agrochemical/materials/medical industries.

| 研究実績の概要 |
Until now, the following research achievements have been achieved.
1. The synthesis of stable Mn(III) aryl complexes obtained by oxidative addition of aryl bromide or aryl chloridehas been finished.
2. The reactions of our synthesized complexes with a range of organometallic alkylating or arylating reagents (alkyl and aryl Grignard reagents, MeLi, ZnMe2) to undergo C(sp2)-C(sp3) or C(sp2)-C(sp2) bond coupling has been carried out and a preliminary catalytic system has been demonstrated.
3.The reagent scope and yield of the C(sp2)-C(sp3) coupled product can be increased by addition of TEMPO as an oxidant generating alkyl radicals.
4.Except aryl bromide, the type of Ar-Cl is also a good pre-cursor in oxidative addition to MnI species for construc-tion of new C-C bond.
